She's not in the dark on the state of her marriage, but it was lights out for Katy Perry recently during a visit to the Chateau Marmont. The singer, there with a group of friends, had to navigate the venue with candles after a power outage cut all the lights. The singer eventually grabbed a few couches and continued to enjoy the evening by candlelight. "It was hectic but fun," an onlooker tells PEOPLE. – Jennifer Garcia
